NORWOOD, Mass.--(BUSINESS WIRE)--Analog
Devices, Inc. today introduced a high-performance clock jitter
attenuator designed to support the JESD204B serial interface standard
for connecting high-speed data converters and field-programmable gate
arrays (FPGAs) operating in base station designs. The JESD204B interface
was specifically developed to address high-data rate system design
needs, and the 3.2-GHz HMC7044 clock jitter attenuator contains
functions that support and enhance the unique capabilities of that
interface standard. The HMC7044 delivers 50-fs jitter performance, which
improves the signal-to-noise ratio and dynamic range of high-speed data
converters, and the device provides 14 low-noise and configurable
outputs that provide flexibility in interfacing with many different
components. The HMC7044 also offers a wide range of clock management and
distribution features that make it possible for designers of base
stations to build an entire clock design with a single device.

In base stations applications there are many serial JESD204B data
converter channels that require their data frames to be aligned with an
FPGA. The HMC7044 clock jitter attenuator simplifies JESD204B system
design by generating source-synchronous and adjustable sample and frame
alignment (SYSREF) clocks in a data converter system. The device
features two phase-locked loops (PLLs) and overlapping, on-chip,
voltage-controlled oscillators (VCOs). The first PLL locks a low-noise,
local voltage-controlled clock oscillator (VCXO) to a relative noisy
reference, while the second PLL multiplies the VCXO signal up to the VCO
frequency with exceptionally little added noise. For cellular
infrastructure JESD204B clock generation, wireless infrastructure, data
converter clocking, microwave baseband cards and other high-speed
communications applications, the architecture of the HMC7044 offers
excellent frequency generation performance with low phase noise and
integrated jitter.
